Doc Block posted:didn’t they have to keep a microvax emulator running to be able to talk with the chandra x-ray telescope because some dumbass in the early 90s thought basing the telescope flight computer and its ground control systems on DEC hardware and VMS was a good idea, and by the time the damned thing was actually in space it had become clear that it wasn’t? the bets weren't that clear-cut in the early 90s though, vms was at least big enough that it was clear *some* path would exist

really any actual difficulty arising from this sort of thing is more an indictment of the shortsightedness of software backwards compatibility than it is an indictment of the engineers at e.g. nasa or cern not that it seems they have any real trouble, they have their emulators and specific distros, it is just important to remember that it likely makes all kinds of sense in reality to take that route than the average programmer, with a deprecate-and-forget attitude, will by habit think. software compatibility is good and not that expensive, it just annoys pampered coders working on it
